The yield of a well is the rate at which water percolates into the well under the safe maximum depression head or the critical depression head. It depends on the position of the water table, permeability, and porosity of the soil, rate of water withdrawal from the well, and amount of water storage in the well.

The yield of a well depends upona)actual flow velocityb)permeability ...
Yield of a well depends upon actual flow velocity, permeability of soil, and area of aquifer opening into the wells. Let's understand each factor in detail:
Actual flow velocity:
The actual flow velocity refers to the speed at which water flows into the well. The flow velocity is influenced by the pressure gradient, which is determined by the difference in water levels between the well and the surrounding aquifer. The greater the pressure gradient, the higher the flow velocity, and the greater the yield of the well.
Permeability of soil:
Permeability is the ability of soil to allow water to flow through it. The higher the permeability of the soil, the greater the yield of the well. This is because water can flow more easily through highly permeable soils, allowing more water to enter the well.
Area of aquifer opening into the wells:
The area of the aquifer opening into the well also affects the yield of the well. The larger the area of the aquifer that is in contact with the well, the greater the yield of the well. This is because more water can enter the well from a larger area of the aquifer.
Conclusion:
In summary, the yield of a well depends on several factors, including actual flow velocity, permeability of soil, and area of aquifer opening into the wells. These factors are interdependent, and all of them must be taken into consideration to determine the yield of a well.
